Ever dreamed of recording your dreams and turning them into a video clip? The technology that enables you to do that is near: UC Berkeley scientists figured out a way to turn the way our brains interpret visual stimuli into a video, and the result is amazing.
To be able to do this, the researches used functional Magnetic Resonance Imaging (fMRI) to measure the blood flow through brain’s visual cortex. Then, different parts of the brain were divided into volumetric pixels or voxels (the term might be familiar to those who remember early 3D games which were based on voxels instead of polygons which are more commonly used today). Finally, the scientists built a computational model which describes how visual information is mapped into brain activity.
